Wondering about that super duper El Nino? CPC has you covered cpc.ncep.noaa.gov/products/ana...

JFM 2026 RONI weighs in at -0.72 as cool ENSO conditions continue

An actuary, a lawyer, and a climate risk scientist walk into a bar (meet on Zoom). This is the result: eartharxiv.org/repository/v...

is there place to download a reasonably updated archive of daily RMM12? Or should I be using another MJO index? this seems to end in 2024? www.bom.gov.au/climate/mjo/...

I was told "We need a climate stripes for ENSO"

I love writing about geeky science that has real-world implications. In this case, a new NOAA index does a more solid job of classifying El Niño and La Niña—and that helps explain some recent puzzling events. @climateconnections.bsky.social yaleclimateconnections.org/2026/02/a-ne...

🌪️ Happy to share this new paper from @mktippett.bsky.social and I. We constructed a synthetic event set for U.S. tornado outbreaks. It has 200,000+++ events, which can be boiled down to resolve localized risk, and we detect robust shifts in activity due to ENSO and trends. doi.org/10.5194/nhes...

📣 New paper with Lorenzo Polvani published in @agu.org GRL! Increasing Frequency and Persistence of the Summertime Greenland High Regime Not Captured by a Seasonal Prediction Model Very Large Ensemble Open access: doi.org/10.1029/2025... @earthscista.bsky.social @lamont.columbia.edu

I was talking to a colleague on Friday and he said, oh, I didn’t know you wrote a book?? and clearly I have not been obnoxious enough anout this. So: I wrote a book. Some people thought it was good. You should read it www.scientificamerican.com/podcast/epis...

A climate projections 101:

especially important since the iri dl is on its last legs

This new paper is about which of Mike’s favorite topics: a. ENSO b. tropical cyclones c. NMME forecasts d. all of the above agupubs.onlinelibrary.wiley.com/doi/10.1029/...

more chiclet, more better

🚨 New paper alert! 🚨 The correlation between ENSO and Tropical Cyclone activity in the Pacific has strengthened in the recent decades. Meanwhile, there is a multidecadal oscillation in the ENSO-Atlantic TCs teleconnection strength. 🔗 dx.doi.org/10.1029/2025...

The IRI DL is a uniquely valuable resource for NOAA (and more) climate data. Over the last 27 years it had a huge impact (positive!) on my career. So long, and thanks for all the fish!

Also have you wondered about using ADT-HURSAT for intensification analysis but didn’t want to download nine csv files from the SI of a PNAS paper?

Have you wondered about trends & ENSO variability in Atlantic TC intensity/intensification? @scamargo.bsky.social and I did. journals.ametsoc.org/view/journal...

Oh you sweet summer child.

seasonal forecast models aren’t just for making seasonal forecasts

Surely this will be the payment that finally gets the extortionist to stop demanding money

This fellowship was a huge part of the reason I am continuing to do climate science, and it has supported so many incredible people. These effects on early-career researchers, who do some of the most impactful work, is going to have long-lasting implications for science and scientists.

if only there were something like a library for data

Latest NMME ENSO forecasts are cooler (0.25–0.5 °C) than last the ones from last month. (I don't have CFSv2)

I made a (probably incomplete) local copy b/c the enso blog is my source for all things enso. Backup sites? There’s always the wayback machine web.archive.org/web/20250623...

So long, and thanks for all the fish! 😢https://www.climate.gov/news-features/blogs/enso/hitchhikers-guide-june-2025-enso-update

This is a giant loss. The ENSO Blog in particular was an invaluable resource.

It’s been a joy to be a contributor to the climate.gov Polar Vortex blog the last two years- we had so many more topics we wanted to cover. It’s been a real outlet for me to share my love of the atmosphere. 💜 www.theguardian.com/us-news/2025...

I don't even know what to say. Climate.gov is where I became a science communicator. They took a chance on a funny scientist and let me be me (weird analogies included.) Climate.gov is an example of not just government done right, but Comms done right. Pick up these folks asap.

Home of the ENSO blog and more www.theguardian.com/us-news/2025...

How do a climate-scale patterns, like La Niña, influence extreme weather events, like tornado outbreaks? I break it down in this ENSO Blog post, plus discuss this hyperactive 2025 season in particular. 🌪️

@kmalloy.bsky.social talks ENSO and 🌪️

It's outrageous that NASA GISS, one of the best earth & space science labs in the world, is being kicked out of its Columbia home. The outstanding scientists who work there can't say that publicly, but I can. And so can you --- call your reps, esp. (but not only) if you live in NYC or NY state.

🌧️📉 Can we predict tropical cyclone precipitation (TCP) at subseasonal scales? Our new study shows that biases in TC occurrence forecasts limit skill in TCP (and total rainfall too!) With @mktippett.bsky.social and @scamargo.bsky.social journals.ametsoc.org/view/journal...

Thunderstorm research lead at Gallagher with multiple locations available, requires a PhD in climate/atmospheric science/meteorology

A major loss to our understanding of how extreme weather events are affecting us. There are 3 alternative databases I will be using: Gallagher Re: www.ajg.com/gallagherre/... Aon: img.clients.aonunited.com/Web/Aon5/%7B... EM-DAT: www.emdat.be
